Sogang University Department of Physics professor Park Jeong-hyuck’s article was published in “Physical Review Letters” issue of October 2015. This academic journal has been acknowledged as the most prestigious journal in academic world of physics. This research was carried out as a joint research with professor Choi Kang-sin (first author) from Ewha University and professor Park Jeong-hyuck as a corresponding author with the support from National Research Foundation of Korea.

Professor Park Jeong-hyuck from the article “Standard model as a double field theory”, predicted that the Standard Model of spin group can be reformulated as a double field theory and suggested to the academic world of physics to verify this with experiment.

For the last 5 years, research team of Professor Park Jeong-hyuk has been developing differential geometry appropriate for string theory, which introduced basic structure of particle with string. As the result, already concluded research results which restructured and unified the string theory that connotes supersymmetry theory. Professor Park Jeong-hyuck and professor Choi Kang-sin from Ewha University applied preceding research results related to string theory to the Standard Model of particle physics and suggested that the Standard Model of spin group can be reformulated as a double field theory unlike the existing research results.

This research result of the fact that the spin group can be reformulated as a double field theory is expected to have great ripple effect in overall academic field of particle physics. Professor Park Jeong-hyuk said, “It is especially meaningful because the prediction of double field theory on lepton and quark can be verified in the future with accelerator experiments and so on.”
